. Specification of Letters Patent.

Patented Get. 23, 1917.'

Application filed February 28, 1917. Serial No. 151,386.

To all whom 'it may concern:

Be it known that I, LEoN M. GIRoUX, a citizen of the UnitedStates, and a resident of New York, in the borough of Manhattan, county of New York, and State of New York, have i'nvented certain new and useful Improvements in Lamps, of which the following is a specification.

This invention relates to improvements in and relating to lamps, and particularly lamps for automobiles, aeroplanes,y motor boats, 'or the like. An object of the invention is to provide a lamp of this character which will be artistic in appearance, of such shape as to' form practically no resistance to the wind, and having lines which harmonize with the well-known stream line type of car, thereby giving an added appearance of speed and grace toY such cars. lAnother object is to provide in such a lamp, lighting means by which light may be dissegninated and reflected in all directions therefrom, ahd to this purpose, I propose to provide an opening at the front, openings extending radially around the body of the lamp, and an opening at the rear, all

provided with'suitable lens, colored glassand'the like, and alighting means whereby flight may be reflected in all directions through the various openings.

lVith Ithese and other objects in view, em-

bodimentsv of my invention are shown in the accompanying"drawings, and these embodimetns willI be hereinafter more fully described with reference thereto, and the invention will be finally pointed out in the claims.

In the drawings,

Figure 1 is a side elevation of my improved lamp;

Fig. 2 is a sectional view thereof;

Fig. 3 is a modified form of construction;

Fig. 4 is a section on the line 4L-4= of Fig.

2, and Fig. 5 is a section on the line 5--5 of Fig. 3.

Similar' reference characters indicate i p corresponding parts throughout the several threaded liange, which is screwed into the section 10` for securing the sections together. In the foi-xn illustrated, the Ygeneral contour .of the lamp is bullet or torpedo shaped, but this it will be understood may be changed as desired. The forward portion of the member 10 has an inwardly tapering tubular member 12,y arranged therein, at the ends of which are mounted the lens 13 and 13a, and a reflector 14; is provided at the rear of the sai-d member, a lamp socket 15 being secured centrally of the said reflector. An electric incandescent lamp 16 is provided in the said socket, and current is supplied to the same by means of wires 17, which extend at the rear of the reflector 1l through the sides of the lamp, and. a bracket 18 provided on the lamp for securing the same to the automobile or other vehicle.

Radially arranged in the sides of the lamp about the incandescent lamp 16 are a plurality of longitudinally disposed openings 19 suitably spaced apart and provided with glass inserts 20, which-may be red, blue, or any desired color.y These may also be in the form of bulls-eyes', but the elon gated shape is preferred, as this gives the desired appearance of speed and also more effectively distributes the light rays. Another opening 21 is provided in the end of the member 11, in whichis inserted a glass piece 22, through which. lightrays are directed from the incandescent lamp 16 by means ofapertures 23 provided in the re- Hector 145. This clearly defines the length and appearance of the lamp at night, and4 also indicates to anyone at the rear of the lamp that the same is lighted.

The `foregoing construction is particularly adapted, for the side-lights of automobiles, but in Fig. 3 I have shown a form of my invention to be used as a headlight. rIhe general shape and arrangement 'of the lens and glass inserts are practically the same as in my lirst construction, vbut a reflector 24 is arranged immediately behind the front lens 25, both the lens and the reiiector being held in vplace by means of a,ring 26 threaded .or otherwise suitably secured to the front of the reflector and held in position by' a bracket '.llhe lamp 2Q reiiects light through the openings in the sides and in the end the lamp. The wires 32 for both incandescent lamps pass ythrough the side of the lamp and through a bracket 33 for supporting Lhe same. l' a lilith the Vuse of my improved construe* tion, a Very attractive lamp is provided by which a. great amount of light is given by means or a very small. amount of lighting power, and the lamp is clearly visible in all directions. it the saine time, the elongated lens in the side ot the lamp, together with 'the taper-ine' to the rear portion of the small rear lens gives an appearance of great speed and grace. "y

l have illustrated and described preferred I and satisfactory embodiments of my invention, but it is obvious that changes may be made therein Within the spirit and scope thereof, so that l do not Wish to be limited to the particular form shown except as may be required by the claims.

claim:

A lamp of the character' described con.M prising an elongated casing tapered toward one end nid provi-ded W'th. a lens at one end und with a circular series ott translucent prisms peripherally disposed around its body portion, and on electric lamp socket mounted in said casing and adopted to hold a lamp bulb opposite seid `,perphcra'l prisms in position to emit light rays forward through seid lens and radially through said prisms around said body.

2. :i lamp of the character described comprising an elongated casing tapered toward. one end and provided with a lens at one end and with a circular series of translucent pri' ns periplier; ily disposed around its body fetii'c lamp socket mounted in portion, un el seid casi and. adapted to hold a lamp; bulb josit f. id peripheral prisms in position to emit lieht rays forward through said lens and rado y through said prisms around and said bod conireflector back of infieeeo said circular series ot' prisms and adapted to reflect rajjfs therethrough.
